Filterjam is a multi-band resonant filter delivering weird ringmod-like filtered sounds. The input signal is divided into 4 bands that are then summed or multiplied together according to the selected mode. Filterjam can be very harsh or gentle, it can add brightness or depth to synth sounds, but it can also completely mangle acoustic sources. ## Key features - Multiband resonant filtering - 4-band signal division - Sum or multiply band modes - Versatile sound shaping - Ringmod-like effects ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/filterjam/id1659941144/reviews.md ### 5/5 — Nice *2025-07-21* Super dope in adding flavour or sauce.

In particular his apps with hainbach would be perfectly suited to iOS and I am incredibly glad that he is porting them over so I can buy them again to use on my iPad! Filterjam is a brilliant Christmas present, a wonderful, musical filter app that will take you back to the days of experimental electronic music trailblazer by the likes of the RAI Musical Phonology Studio, WEM, RDF, EMS and of course the BBC Radiophonic workshop. A filter like this should be part of every iOS musicians toolbox for pinging heaven! ### 5/5 — Awesome filter *2022-12-25* Thanks! Would be great to see the rest of your desktop plugins as AUV3 fix and instruments! ## Frequently asked questions about Filterjam ### What kind of sounds can Filterjam create?
